What do you mean by "notchiness"? I generally consider that a good aspect of a shifter ("notching" into each gear). Is that not what you're referring to?

Also, I assume all this talk is concerning the BMW SSK. How does it compare to the UUC SSK? I dislike the stock shifter, and am looking for something that feels more solid and notches into each gear more. Don't really care about throw length.

The previous owner had the BMW Performance SSK installed through the dealer. You have to be extremely precise to switch gears quickly. If you're even a little to the left or rights, you will get stuck.

I haven't tried any other SSK's. There's always the slim possibility they work better.
